Lounge bar open til late in Florence

I was asked in many cases advises for a place open until late at night, in Florence, Italy.
Well here it is, Pantheon lounge in Via della Fornace, just before the Rooms club in Piazza Ferrucci.
I was skeptical after reading an article in another web site but then I decided to try. A fantastic setting made with sofas, mirrors, soft lights. A perfect place where you can sit and relax in comfortable sofas while you chat with friends: they are open until 3am! The cocktails are nothing special and the music is too loud for me but this is really a nice place. Night birds this is the right place for you!
